FLASHING BIOS - THE PROCEDURE

BIOS Update Procedure

All latest Motherboards today,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With
FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.
Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about
this.

Please read the following instructions in full before starting a Flash BIOS upgrade:

A. Create a Bootable Floppy (in DOS)

•With a non-formatted disk, type the following:

format a:/s

•If using a formatted disk, type:

sys a:

This procedure will ensure a clean boot when you

are flashing the new BIOS.

B. Download the BIOS file

•Download the correct BIOS file by clicking on

the file name of the BIOS file you wish to download.

•Save the BIOS file and the Flash Utility file in the boot disk you have created. Unzip the BIOS file and the flash utility file. If you don't have an "unzip" utility, download the WinZip from www.winzip.com or www.pkware.com. Most CD ROMs found in computer magazines, have a shareware version of WinZip on them.

•You should have extracted two files:

Flash BIOS utility eg: flash7265.exe (for example)

BIOS eg: 6152J900.bin (example)

Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.

C. Upgrade the System BIOS

During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22

•At the A:> prompt, type the corresponding Flash

BIOS utility and the BIOS file with its extension.

For example:

flash625 615j900.bin

•From the Flash Memory Writer menu, select "Y" to

"Do you want to save BIOS?" if you want to save (back up) your current BIOS (strongly recommended), then type the name of your current BIOS and its extension after FILE NAME TO SAVE:

eg: a:\613J900.bin

Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.

•Select "Y" to "Are you sure to program?"

•Wait until it displays "Message: Power Off or

Reset the system"

Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system. If you write to BIOS but cannot complete theprocedure, do not switch off, because the computer will not be able to boo, and you will not be given another chance to flash. In this case leave your system on until you resolve the problem (flashing BIOS with old file is a possible solution, provided you've made a backup before)

Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.

For AMI BIOS

Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.

BIOS Update Tips

Note:
1.Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to.

(This option is not available when flashing an AMI BIOS).

2. If you have problems installing your new BIOS please check the following:

Have you done a clean boot?
In other words, did you follow the above procedure for making a bootable floppy? This ensures that when booting from "A" there are no device drivers on the diskette. Failing to do a clean boot is the most common cause for getting a "Memory Insufficient" error message when attempting to flash a
BIOS.If you have not used a bootable floppy, insure a clean boot either

a) pressing F5 during bootup

b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by

using the EDIT command.

Have you booted up under DOS?
Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers.

Important:
Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above

procedure (format a: /s and rebooting from a:\).Have you entered the full file name of the flash utility and the BIOS plus its extension?
Do not forget that often you will need to add a drive letter (a:\) before flashing the BIOS.

Example: when asked for file name of new BIOS file which is on your floppy disk, in case you're working from c:\ your will need to type

a:\615j900.bin, rather than 615j900.bin only.

how can recover a flashed/deleted/upgrade failed bios


Download the latest BIOS update from your computer manufacturer's website onto a USB flash drive. Refer to your user manual to obtain the manufacturer's website address.

If the downloaded BIOS file is a zip archive, unzip the contents onto your USB flash drive.


Jumper settings may need to be reconfigured on some motherboards to enter BIOS recovery mode. Most Intel-based motherboards have a jumper setting or switch near the on-board


CMOS battery.

The procedure for setting the jumpers will vary depending on your motherboard make and model, so refer to the motherboard documentation for specific instructions.

Power on the computer and press "F2" to access the Setup Mode menu.


If you are unable to access the setup menu, you will not be able to proceed with this repair. Take your computer to a repair shop, as the motherboard may need to be replaced.


Use the arrow key to select "Boot Priority" or a similarly named field. Press the "Enter" key.


Scroll down until "First boot priority" or "First boot drive" is selected and press "Enter."


Select the USB flash drive as the first boot priority device. Press the "F10" key to save this setting and exit from the setup menu.


Connect the USB flash drive to an open USB port on your computer.

Then let your computer fully reboot.

The USB flash drive should be detected and the BIOS should update automatically.


When the update is complete, you may be prompted to restart your computer, or it may reboot automatically.


If you are able to use your computer without any further problems of overheating or failure to recognize drives, your failed BIOS update has been resolved.


hope this helps

How to Reflash Motherboard BIOS About updating BIOS... The whole BIOS updating procedure should be treated with extreme caution. If you do not encounter any system instability or bugs with the current BIOS version, we suggest that you keep it. If you determine to flash BIOS, you are taking a personal risk of BIOS flash failure. Please contact your supplier or our distributors/resellers for further remedy in case system crashes unfortunately because of BIOS flash failure. Before you begin... 1. Please make sure the BIOS version you want to flash matches your motherboard model. 2. If your BIOS is flash protected, please do not enable BIOS Flash Protection under Advanced CMOS Setup (AMI BIOS) or Advanced BIOS Features (AWARD BIOS) in BIOS menu. 3. Never interrupt when you BIOS is being updated. 4. Because BIOS flashing is potentially risky, if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in system malfunction. Three BIOS Flash Utilities... We provide three BIOS flash utilities at our website. Below are the overviews. 1 : flashbios_qflash.gif A BIOS flash utility embedded in Flash ROM. Not all motherboards have the Q-Flash, please use @BIOS or DOS flash utility to update BIOS if your motherboard does not have Q-Flash.

where can I find info to setup bios. also how do I upgrade bios


Hi,
For this you need to know the exact model of your motherboard. Your current BIOS firmware version can be seen in the BIOS setup window itself ( Press DEL key during your system startup to enter into BIOS screen)
Your motherboard should have Flash BIOS so as to upgrade its firmware. All latest motherboards will have this type only. Goto your motherboard manufacturer website and search for latest BIOS firmware for your exact model. There itself you can find the utility required for BIOS. download that utility and using which you can update your firmware. Please do update your BIOS only if it is required.
I hopt his is helpful to you
